8.5x3.0 Inner Tube – 90 Degree Bent Valve for Electric Scooters (Heavy Duty Replacement Tube)

Upgrade your ride with this 8.5x3.0 inner tube featuring a 90° bent valve, designed specifically for wide 8.5” tyres used on many popular electric scooters.

The 90-degree angled valve stem allows for easy access in tight motor hubs, making inflation faster and reducing strain on the valve—one of the most common failure points in inner tubes.

Constructed from durable butyl rubber, this tube offers excellent air retention, puncture resistance, and long service life, making it ideal for daily commuting and high-performance scooters alike.

⚡ A must-have spare for riders who want reliability and hassle-free maintenance.
